Brine Draw Failure in Sears, GE Smart Water, North Star Systems

Here is what causes suction failure in order of importance and frequency:

1 ) Gasket under Nozzle Venturi is worn, cracked, or "dried out".
2 ) Seal Kit is failing at some critical area, and not sealing.
3 ) Rotor Disc is no longer smooth and even, resulting in lack of seal
during critical valve functions.

So, the best recommendation is to replace all 3 parts, unless you feel very
confident of the condition of one or more of the parts and there fore don't need replacing ( yet ).

*** Suction FAILURE Can Be Related To:
1 ) Gasket under Venturi ( sometimes the Venturi too ).
2 ) Seal Kit orings ( any leakage internally effects suction )
3 ) Rotor Disc ( any scratches or uneven wear effects suction )
4 ) Drain flow ( blockage of Drain Flow Plug or Drain hose effects suction... or Drain hose running UP HILL )
5 ) Bottom Flow Plug in the Nozzle Venturi Assembly, if closing up ( should be 0.3" I.D. hole )
6 ) Poor seal of the Nozzle Venturi Assembly to the Valve body ( oring pair 7170319 ).
**** Anything else would be a clogged screen ( two in Nozzle Venturi and one at bottom of Brine Float Assembly )

*** And last but not least, if you have being using Pellet Salt for many years, it could be clogging the bottom of your brine well, and limiting flow at the bottom of the salt tank.
Pellet salt leaves a hard undissolvable mush of 1 - 3 inches per year of normal use. And eventually will clog the flow through the brine well at the bottom of the salt tank area.
